TI Announces Very Low 4ppm/C Drift, Micro Power Voltage Reference Family in Tiny SOT23-6 Package

Jul 5, 2005

DALLAS (July 5, 2005) - Texas Instruments Incorporated (TI) (NYSE: TXN) today introduced the REF32xx, a 4ppm/C temperature drift, high accuracy, voltage reference family from the company's Burr-Brown product line. The micro-size SOT23-6 packaging and micro power consumption make this product family ideal for portable and battery-operated applications, medical and test equipment, as well as data acquisition systems. (See www.ti.com/sc05144.)

The REF32xx features high output current of +/-10mA and is stable with any capacitive load. To increase precision, the REF32xx uses force and sense pins that allow 4-wire "Kelvin" connection measurement to effectively eliminate the impact of contact and trace resistance. Other features include low quiescent current of 100uA, with a maximum quiescent current over temperature of only 135uA. Typically, the quiescent current changes less than 2uA over the entire supply range.
The REF32xx can be operated from as low as 1mV from the desired output level under the normal load conditions. When shut down, the output goes to a high-impedance state and current is reduced to ~1uA.
All models in this product family are specified for the wide industrial temperature range of -40C to 125C and offer low temperature drift

Available Today

The REF32xx is available now in the micro-size SOT23-6 package from TI and its authorized distributors. The device is priced from $1.70 in 1,000 piece quantities (suggested resale pricing).
